Note: This post is a follow-up to the chapters in my 2018 book about visual experiences of spatially distant things, things that are at some depth in one’s visual experience.
Note 2: All illustrations are by me. This is why they are not very good.
It is common to talk about the direction of vision, visual direction, or line of sight. It is common to talk generally about where things are located visually and to talk about a direction in vision.
